Running Lingua Franca IDE (Epoch) with Kotlin based Code Generators Enabled (without Eclipse Environment) - lf-lang/lingua-franca GitHub Wiki

You can use the Lingua Franca IDE (Epoch) for Kotlin-based code generators even without the Eclipse-based setup. You need Maven (mvn command) installed on your machine a priori.

For macOS X, inside the Lingua Franca repository (in this example, lingua-franca-intellij), run:

mvn package

You may need to clean first:

mvn clean

This may still fail with missing packages, in which case you can force updating all packages like this:

mvn -U package

If you have some Xtend code (which we no longer have in the LF repo), then mvn may also fail with errors due to cached Java code generated from Xtend, for example:

[ERROR] /Users/hokeunkim/Development/lingua-franca-intellij/org.lflang/xtend-gen/org/lflang/generator/CGenerator.java:[652]
[ERROR] 	final String cFilename = this.getTargetFileName(this.topLevelName);
[ERROR] 	                              ^^^^^^^^^^^^^^^^^

In this case, you can use gradle to forcibly clean all cached data from the previous build with the following command:

./gradlew clean

If the mvn package command succeeded, now you can find the built Lingua Franca IDE in the target directory. For macOS X, run the following command to locate and run the Lingua Franca IDE.

cd org.lflang.rca/target/products/org.lflang.rca/macosx/cocoa/x86_64/epoch.app/Contents/MacOS
./epoch

In Linux, you can find the executable for the Lingua Franca IDE as follows.

cd org.lflang.rca/target/products/org.lflang.rca/linux/gtk/x86_64/epoch
./epoch

You can use the graphical interfaces (diagrams) and the compilation with the Lingua Franca IDE for the Kotlin-based code generators, including C++ and TypeScript.
